How to Fix CVE-2018-1190

To remediate this vulnerability, upgrade all affected Cloudfoundry identity server dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

org.cloudfoundry.identity:cloudfoundry-identity-server fixed: 3.20.2 
<dependency>
    <groupId>org.cloudfoundry.identity</groupId>
    <artifactId>cloudfoundry-identity-server</artifactId>
    <version>3.20.2</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=org.cloudfoundry.identity

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2018-1190, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.cloudfoundry.identity

Analyze the terminal output to locate any version of Cloudfoundry identity server in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.20.2), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.cloudfoundry.identity command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Cloudfoundry identity server, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

An issue was discovered in these Pivotal Cloud Foundry products: all versions prior to cf-release v270, UAA v3.x prior to v3.20.2, and UAA bosh v30.x versions prior to v30.8 and all other versions prior to v45.0. A cross-site scripting (XSS) attack is possible in the clientId parameter of a request to the UAA OpenID Connect check session iframe endpoint used for single logout session management.
